ANTI-SLIPPING SANDAL 0R SHOE.

.To ail whom it 71mg/ concern.- I

Be it known that I, JAMES NV. WHITE, of the city and county of Philadelphia, in thel State of Pennsylvania, have inventedl certain newandusefulImprovements inAnti-Slipping vSandals `or Shoes, of which the followingr is a specification. l

Antislipping shoes have been made with ythe points being either permanently fixed` to the shoe or removable therefrom at pleasure. One of the common forms is to have the projecting points, spurs, or catches attached to or formed with a removable platey held to the sole or heel of thel shoe by clamps or straps. Sandals or'overshoes have also been made with a idouble sole of leather having an intermediate p latev secured therein, with points or spurs projecting from the outer side of the plate through the lower thickness of the leather sole. All the anti-slipping arrangements or ice-'ereepers, so far4 as I am aware, have some objectionable feature, either by'reason of the difficulty of securing the spurs or points to the sole or heel, orby reason of the liability of the same to become detached while in use, causing either inconvenience or loss. Some while others, though comparatively economical, are less efficient for .the purposes for which they are designed.

The object of my present invention is to provide an improved sandal or shoef, which can be rendered anti-slipping by the attacha ready and economical manner, the anti-slip# ping spurs or points being capable either of attachment to the sandals or shoes at the time of Ymanufacture or" of being readily applied theretov at a future time, as may be desired.

The subject-matter claimed is first fully described, and then particularly pointed outat al longitudinal ,section through my' improved thereof. 1

' My improvements are preferably applied to rubber shoes or sandals which the owner wears when he is walking upon wet or slippery places,

and removes when he enters places having covered or carpeted floors.

An ordinary rubber sandal, A,- is shown in the drawings, having water-tight sides and.

55 forward of the hollow part of the foot, is -a thin sole, as usual. Fitting the inside of the sandal metal plate, B; preferably corresponding in-.

shape to the interior of the sole C. This plate has one hole'or a series of holes formedtherein '4 at the junction of the reduced shank with the ltapered or pointed head of the rivet and the U sole I preferably interpose a thin nietal'washer,

d, a little larger in diameter than the cone-head of the rivet, for said headto bear upon, while upon the inner end of the shak of the rivet I also preferably employ a corresponding washer, d', and then rivet the inner or shank end down upon said last-mentioned washer, so as to securely fasten the rivet in place.

It will thus be seen that the sandal or shoe is provided with firm fixed cone points or spurs upon the bottom or wearing surface, whereby slipping of the wearer upon ice and snow is effeetually prevented. In addition, the metal I plate affords stiffness and firmness to the shoe, and the shoe or sandal may be easily secured upon the foot by placing the toe of the foot into 'it'and driving it home by a thrust of the foot;

against the door, the spurs or projections lo ing the outer shoe or sandal, while/the mo'lvef' ment due tothe thrust of the foot dri/ves the foot readily into the sandal, thus permitting of 90v its being readily se'euredto the footwithout nec-. Y

essarily using the hands to pull the sandal on.

I have described the preferred form of con-A struction; but it willbe obvious that, instead of riveting the inner ends of the Shanks of 95 the cone-rivets down upon the stiii'ening-plate B, screw-nuts maybe screwed uponthreads forfned upon the rivet-Shanks, so as to render ca ch rivet separately detachable, whereby,aiter i long use, should any one or more ofthe rivets roo y.is

" have their points orspurs worn, so as to be un- .available as. an. anti-slipping medium, ready accomplished'.

5- .Itwill also be obviousthat insteadof having renewalsof thespurs or projections may be f separate screw-nuts for the Shanks of the rivets,

the holes'in the plate A, into which the rivets arel inserted,1nay be screw-threaded."and that the rivets or spurs may be screwed therein. Again, it is lnot absolutely necessary to inter- .pose between the head of the rivet orspur and the bottom of the sole a separate washer', while it will also be understood that the equiva lent of such interposed! separate Washer would be a thin metal lllate on the bottom of the sole, through which' a l or some of the rivets might be made-to pass.

' Itwill'bereadilyperceivedthatmyimproved Inethod of attaching spurs or projections to the'factory Where the shoes are made or -subsequently..

, Before stating what I claim, it may be well "to'say that I do not broadly claim 'a, shoe 4or shoes'or sandals may-be employed eitherat sandal having projecting spurs extending through the outside of a sole. That, as before indicated, is old, and not my invention.

What I claim herein is- 1. The combination, Witha shoe, of a shouldered spur projecting from the .shoe-bottom, and a lfastening for said spurrat the inner side of the shoe, substantially as described.

2.v In .a shoe, the combination of a shouldered spur projecting from the shoe-bottom, a washer 'interposed between the shoulder .of said spur and the outer side of said shoebottom, and a plate at the inner side of the shoe, through which the shank of the spur projects, andy to Whichvit is fastened by riveting or in other equivalent ways, substantially as described.

In testimonyl whereof lI have hereunto subscribed my .name this 1st day of February, A.
